COCKLE-SEPARATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 256,674, dated April 18, 1882. Application filed October 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. GoR'roN, acitizen of the United States, residing at Eau Claire, in the county of Eau Claire, in the State of Wisconsin, have invented certain new and useful Improvements in Cockle Separating Machines, of Which the following is aspecification.

My invention relates to improvements in machines employed to separate cookie, garlic, and other small seeds from wheat or rye or other grains; and its object is to provide an efficient separator having an increased capac- Fig. 4, a transvers vertical section of the hopper or receivin g-end portion cut on the dotted line y, Fig. 2; Fig. 5, a transverse vertical section of the delivery-end portion cut on the dotted line a: as, Fig. 2; and Fig. 6 represents a section of the outer perforated cylinder, sho wing the stavejacket connection therewith. Fig. 7 is a transverse vertical section of the delivery end on dotted line Z, Fig. 3; and Fig. 8 is an enlarged transverse vertical section of the delivery-end portion of the perforated cylinder and its attachmentson dotted line :0 .r, Fig. 2.

Inthe figures, A represents the lengthwise or side sills, and B the end or transverse sills, of a frame rectangular in plan.

At 0 are represented corner and interme'-' diate posts, which are framed or otherwise suitably joinedto the side sills, from which they rise and support the lengthwise beams D,

which are framed or otherwise securely fixed ontheir upper ends.

At E are represented transverse beams, suitably framed into or otherwise securely fixed to the vertical posts. These several beams are of suitable dimensions, rectangular in section, and framed or joined to each other in the manner and form shown and described, and constitute the supporting-frameof myimproved machine. I

At F is represented a conveyer-shaft, suitably mounted to revolve in hearings on the transverse beams centrallyin the width of the frame, having one of its end portions provided the shaft. This shaft is slightly inclined, being highest at its head or conveyer end.

with spiral oonveyer-blades a, suitably fixed to At G is represented a. hopper provided with a horizontal tubular portion, 12, adapted to receive the conveyer portion of the shaft F. This hopper is fixed to the inner side of the trans: verse end bar of the frame in such position thereon thatits tubular portion will be concentric with the conveyer-shaft, and will incase the conveyer portion thereof in such a manner that the revolutions of the shaft will carry the grain depositedin the hopper through the tubular portion thereof.

At H is represented a cylinder made from plate material, perforated, and mounted upon the conveyer shaft, supported thereon by means of cross-arms c, framed into the shaft at right angles to each other. This perforated cylinder is provided at one end with a head, 0, having a central opening to receive the tubular bearing of an outer cylinder.

At I is represented a cylinder made from perforated-plate material, and of greater di ameter than the inner perforated cylinder, E. This cylinder is provided with ends d, to which the perforated-plate cylinder is fixed. These ends are provided with axial tubular journals (1 and d", of which the tubular journal (1 receives the tubular portion 1) of the hopper in such a manner as to revolve thereon freely.

At 6 and c are represented annular rings, placed on the outside and end portions of this perforated cylinder, between which this outer perforated cylinder is provided with a jacket, made in stave-like sections 0*, having their end portionsfitted with hinged arms 6, the hook-end portions of which are pivoted in the annular rings in such manner that the several stave-like portions forming the jacket are independently hinged and capable of opening outward from and closing ontothe perforated cylinder independently, and when closed form a close-fitting jacket to the cylinder. These stave-like portions, toward-their ends, are provided with outward-projectin g arms 0", preferably of some elastic material, as leather or rubber, and are of suitable form and size to extend outward through suitable openings in the, outerjacket.

Atfisrepresented ametallicdisk-head, fixed to the outside of the end din the head end of the outer perforated cylinder. This metallic disk-head is of greater diameter than the perforated cylinder and extends beyond its periphery.

Atf is represented an annular ring, the outer diameter of which is the same as the disk-headf, and its inner diameter is of proper dimensions to-receive the perforated cylinder, on which it is placed in position near the delivery end thereof.

At It is represented a close-fitting jacket, placed upon the perforated cylinder I between the annular rings 0 and f, employed to close the perforations between the rings; but this jacket may be dispensed with when that portion of the cylinder over which this jacket is placedis not perforated. This perforated cylinder, near its delivery end, outside of the annular ringf, is provided with delivery or outlet openings IL, through which the cleaned grain is discharged from the cylinder.

At J is represented an outerjacket of plate material, supported on the periphery of the disk-headf and annular ringf. Thisjacket, at proper intervals, is provided with suitable openings, h, to permit the elastic arms 0 to project outward through them.

At h are represented springsin this instance of wire-bent in any suitable form, and fixed to the outside of the outer jacket, having their free ends inserted in holes in the outer end portions of the elastic arms 0' of the several sections of the stave-formed jacket. operating to carry the several staves from the per forated cylinder when in position to be free to rise. The delivery-end portion of this outer jacketis provided with delivery or outlet openings 7%, through which the cockle and other matter separated from the grain is discharged from thejacket. This cylinder, consisting of its several parts, constructed and arranged substantially in the manner hereinbef'ore described and shown, is mounted on its tubular journals to revolve in suitable bearings in a box-like frame, consisting of end beams, K, and side beams, K, suitably framed or joined to each other. This frame, with the cylinder mounted to revolve therein, is supported in position in the main frame to hold the cylinder concentric with the conveyer-shaft by means of spring-bars i, having their lower ends securely fixed to the transverse sills and their upper ends firmly fixed to the end beams of cylinder-supportingframe. Thesespring-bars hold the cylinder in position to rotate on the same axial center of the conveyer-shaft and in such manner as to permit an endwise reciprocating or shivering movement.

AtLis represented avertical transverse spoutlike division within the side walls of the cylinder-frame, formed by means of the vertical transverse walls 7:, which are fixed at their upper ends to a transverse beam, k, fixed to the upper surface of the side beams of the main frame, and at their lower ends are fixed to a transverse sill, k, fixed to the side sills thereof, forming a vertical spout-like compartment, k. The vertical walls of this compartment; are provided with circular openings concentric with the axialcenter ot'the conveyer-shaft, and of proper size to admit the delivery end of the cylinder to permit it to revolve therein freely. The position of this vertical spout is such relatively with the cylinder that the dischargeopenings of the outcrjaeketof the cylinder will be within its walls to discharge the contents of thejacket within the spout. That portion of the spout on the under portion of the cylinder is provided with inclined end walls, K, which are also represented in the dotted lines in Fig. 5, employed to conduct the contents of the spout to the outlet-opening l, which is provided with a hinged door, l, to close the opening against the infiowing current of air produced by the action ofthe exhaust-fan, but will yield to the pressure of the accumulations of the discharges of the outerjacket of the cylinder to permit their discharge.

At M is represented a driving-shaft supported in ahorizontal position ion the outside of the main frame, to revolve in suitable bearings fixed to the vertical posts thereof. This driving-shaft is designed to have a suitable connection with a prime mover, and it is provided with a belt-pulley, m, which is connected with a like pulley, m, by means of a crossbelt, 112'. This driving-shaft is also provided with pulleys a in position to receive the belts n, which encircle the cylinder on the line of the outward-projecting elastic arms 0'.

At a is represented ahorizontalshaft, placed parallel to the driving-shaft, supported to revolve in suitable bearings on the inside of the vertical posts ofthe main frame. On this shaft are mounted idle pulleys n, in the same transverse vertical plane with the pulleys n, and employed to change the direction of the belts a on their under side to cause them to engage the periphery of the cylinder to a greater extent, and consequently to hold the stave-jacket to the periphery of the perforated cylinder to a higher point on their ascending side. On this driving-shaftis mounted a beveled toothed gear-wheel, N, the teeth of which engage the teeth of a beveled toothed pinion, N, mounted on the end of a transverse shaft, N, supported to revolve in suitable hearings on the main frame. This transverse shaft extends to the outside of the main frame, and on its outwardprojecting end is mounted a belt'pulley, P. This pulley is connected with a belt-pulley, R, on the outward-projectingend of a transverse fan-shaft, R, by means of a belt, B. This transverse t'anshaft is supported to revolvein 'suitablebearings on the lengthwise beams of the main frame, and immediately on the inside of its bearings it is made in eccentric or crank form, as at 0, on which are fixed by suitable box-connections spring bar-pitmen 0, having LII with the spout-compartment 76' immediately above the door I of the outlet-opening l. The outer end of this tube connects with its upright portion 19', the upper end of which connects with the open eye-center of the fan-case. By this arrangement a connection of the exhaustfan is made with the chamber of the cylinder,

formed by the ontcrjacket.

From the foregoingit will be seen thatif motion is imparted to the driving-shaftin the direction of the arrow motion will be imparted to the several parts, causing them to rotate in the direction indicated by the arrows thereon, from which it will be seen that the conveyershaft and the innerperforated cylinder mounted thereon and the outer perforated cylinder with its stave-likcjacket and the outerjacket will revolve in opposite directions, and by means of the eccentric and pitman-connection an endwise-reciprocating or shivering-like movement will be imparted-to the cylinder.

It will also be seen that in the rotations of the cylinders the belts a will operate to depress the arms protruding through the jacket and will hold the stave-like jacket to the perforated cylinder while acted upon by the belts, and when relieved from action or pressure of the belts the several independent stave-like portions of the jacket will rise from the pcriphcry of the perforated cylinder by means of the action of the springs connected with the elastic arms projecting from their outer surface.

- In the use ofmy improved machine the grain to be operated upon is placed in the hopper in contact with the conveyor, and with the machine in motion it will be carried by the action of the conveyer into the perforated inner cylinder mounted on the conveyer-shaft and rotating therewith, the action of which will cause the cookie and smaller seeds to pass through the perforations onto the inner surface of the outer perforated cylinder, and the larger grains will be carried on the'inner surface of the inner cylinder, and by reason of its endwise inclination will be discharged from its open end onto the inner surface of the outer perforated cylinder, to be carried thereon and discharged through the outlet-openings h in its outer end. During this operation the cockle and other seeds deposited on the inner surface of the outer perforated cylinder will settle into the perforations therein, resting on the inner surface of the stave-formed jacket, and in its rotations will be carried therein to the point at which the stave-formed jacket is opened from the cylinder, when they will drop from the perforations onto the inner surface of the outer jacket, on which they will be carried on its inclined surface and delivered through the outlet-openings it into the spoutcompartment k, to hedischarged through the openings Z.

From this construction of the parts and the operation it will be seen that the exhaustfan receives its air-supply mainly from the cylin-.

ders, which action will operate to carry from the cylinders through the perforations all light material of a size that will freely pass through the perforations, and will operate in connection with the springs to open the stave-formed jacket, and will also carry outward the cookie and other seeds contained in the perforations of the cylinder.

In a well-constructed machine the springs employed to open the staved-formed jacket may be dispensed with, and the action of the exhaust will be found sufficient to open the stave-like sections thereof.

My machine is capable of use as an eflicient separator without either the inner perforated cylinder or the vibrating or shivering endwise movement; but the omission of both or either of these features will lessen its capacity.

By the employment of cylinders'provided with elongated openings, substantially such as represented at t or t in Fig. 3, my machine may be successfully employed as a grading-machine to separate the smaller from thelarger grains,

,and these may be varied to adapt the machine to grade the various kinds of grain.
